Why mix-up solutions when you want, answers?
Use simplified chemical analysis — and get accurate results quickly. Lab instrument news You can take the tedium out of analysis, with time saving equipment from Hach. NEW Until now titrations have always meant burets, but now imagine a titrator with a DIGITAL readout. The Hach digital titrator is a precision dispensing device that at end-point lets you read the sample concentration directly in mg/L. Twenty-six different prefilled and prestandardized cartridges are available. NEW For the ultimate in titrating convenience, Hach introduces a new compact stir-stand which holds the digital titrator securely while it stirs the sample. White porcelain top resists chemicals.

Spectrophotometers Hach made a simple spectrophotometer into a whole analytical system. The Hach spectrophotometer reads concentration directly on the meter scale, and it comes with 62 different interchangeable meter scales. When used with Hach's coordinated reagents, our extensive system of quality control becomes your assurance of testing accuracy. Now it is available with a flowthrough cell.
Test Kits The most extensive collection of innovative kits in the world—126 kinds. All kits employ improved methods and all are fitted into durable molded cases with step-bystep instructions that make anyone an analyst.

NEW A new laboratory digital pH/mV meter with a direct Fluoride readout joins the Hach pH line. Temperature compensation is automatic with the optional probe or you can set the temperature manually.
Analytical Chemicals The backbone of Hach's analytical systems are the reagents. Thirty years of research have gone into the development of reagents that have high purity, high stability and a consistency you can count on. These same reagents are available in bulk or for custom packaging. Box 389 Loveland, CO 80537
